| 摘要： | Snow and ice on asphalt pavement surfaces can create hazardous driving conditions and nowhere more so than in mountainous areas where the road's geometrical characteristics may aggravate the driving risks. Conventional winter maintenance operations involve sending snowploughs onto roads as well as trucks loaded with salt and other de-icers to clear the roadways after a storm has begun. Although effective, this strategy is costly and labour-intensive and there is often a cost to the local environment where the effects of de-icing chemicals such as brine and solid substances including salt last for months, easily into summer. The consequences can be particularly costly1: 1. an increase in salinity of the earth around drainage areas; 2. fresh and groundwater contamination by chloride, which is toxic to aquatic life even in low concentrations; 3. premature ageing and possible destruction over a shorter time than planned of highway assets such as bridges; 4. high asset-management costs for road authorities, including total replacement years ahead of schedule. |
